You know what makes me happy? Birthdays! And not just mine, although, full disclosure: it will be my birthday in about fifteen minutes. I just love the idea of having a day when all the people in your life shower you with love and attention; that there is one day a year when everyone celebrates you.
Birthdays aren't subject to the usual social constraints that other special, celebratory days are subject to. Birthdays transcend culture and class; you don't have to be in a relationship and you don't need to win any awards or competitions; you just need to be born.
In this world, so full of hate, of suffering isn't it nice to have an excuse to be spoiled or, even better, that you can spoil someone you love?
